To this second part 3 there is screwed one end of the third part 6 of the casing, said third part 6 atV its other end being hollowed out to form a cylinder 7 which communi-- Cates by way of a longitudinal and central borewith the jet orifice 5 aforesaid, and through the wall of Vsaid part 6 there is rovided one or` more small air ports, 9 wiiich communicate with the longitudinal bore 8` aforesaid.

The admissionwof air may be regulated by a grub screw operated by a screw-driver, or, as shown in said Figures 1 and 2,' by means. of a screw 10 provided with a large milled head 11 for operation by hand;

In the cylinder 7 of the ythird part or air intake section 6 there is provided al piston 12, said piston 12, which is a loose fit in said cylinder 7, being provided with three pe ripheral shallow grooves 13, .and also carrying a long thin needleY or wire 14 which extends through the longitudinal. bore 8 of said third part 6 into the jetA orifice 5, said needle or wire 14 being at all times in said jet orifice and serving to break up the water sucked through said jet orifice. Around the periphery of the piston 12 a series of minute holes 15 are drilled for a purpose to be described.

On the third part 6 there screws the fourth part or main body section 16 which envelope the cylinder or cup 7 and forms'an eXpansion and mixing chamber 17. A small chann-elor duct 1,8, whichy terminates ina fine jet orifice. 18a, isdrilled in the part, connects the chamber- 17 with "the con-icalchamber 19 formedinfthe yfemale p ortionl-ofltheipart 6. aforesaid.

Referring now to the modified arrange nient of apparatus or device shown in Fig ure 3 ot the dr wings, this apparatus or deu vice consists oit a three-part casing of cylindrical shape which, when used in conjunction with internal combustion engines for motor cars, is tised in a vertical position ou the dashboard or other convenient place in the car. The first or lower part 1a of the casing is Fitted with a centrally disposed and bored nipple for pipe connect-ion with a water tank located in an@7 convenient position. and at anpT level. The upper end of part 1a is closed by a seating 27 provided with a centrally,v disposed jet orifice 5a therein, whilst in the lower part ot' la two fine ze liters or strainer-s Llare litted.

(in the pper end ot part 1 which part is .L threaded, is screwed the lower end Arind not G", of the casing, a nut ed portion o2 part 1 being n:iid parts 1 and G together adjusted position.

-n the upper end of part G there screws lower end ot yhe third part 16 O' the casir which part 1G" at its lower end is provided with a seating 29 to receive the head of a mushroom valve 30 which is positioned centrallyy within the part G atoresaid. the underside o't said valve 3() carrying a reiiicallv depending' longfine needle or Y( 1l which pesscsthrough a hollow inverted cone ill which by its apex 1s adapted :he close seating on the valve scat 2T c part 1n of the casing. this needle or 'I .l

g Further, a nut 31* on the ortion of the part 1oa is fitted for i gether said parts G and 16a when in required adjusted position; and` further,

d part t5 ot' the casing is provided with 9/ 'tor the admission ot' air, said ports 9 beinp titte/tl or not with means 'lor adjustnient of the passage therethrough of air. flhe cono $31 is a close tit on the needle or The nut serres to lock the parts 1a and G together, after the insertion of the cone 81 the mushroom valve 30. whilst the nut alter regulating the distance between the mushroom valve ffl() :sind its seating 29 in the lower end of part 16a, which part 161l is at its upper end provided with a centrally.' disposed bored nipple Q0 tor a valve-controlled pi e conn-e fion to induction pipe of engine.

The mining oi water and air takes place in the parts 6 and 16 of the casing, water being sucked in through the strainers 4 and jet orifice 5a in said part 1 and split up through its contact with the wall of the cone 31 in said part 6a and further pulverized by the rush of air sucked in through ports 9a in said part 6, the quantities delivered being regulated by screwing in or out the parts 1, 6a and 16a of the casing, whilst the quantity of air may be controlled by suitable means not shown.

The action of the above described modification of the apparatus or device is ent-irely automatic in action, controlled by the suction of the engine, i. e. through the depression which occurs in the induction pipe. Vhen the throttle is close-d or nearly closed (on deceleration or when starting up) the mushroom valve is drawn up against its seating, thus preventing the admission of Water Vapour (Water and air mixture).

From the foregoing description and an inspection of Figure 3 of the drawings, it will be readily understood that no springs enter into the construction of the modified arrangement of apparatus or device; thus there is absolutely nothing to order, or need for replacement.

The control valve or tap may be connected directly to the nipple of the part 16a of the first described apparatus or device, or it may be connected by a fiexible pipe to the nipple of part 16a of either of the described apparatus or device and by another fiexible pipe to the induction pipe, said control valve or tap in these latter cases being located on the dashboard or other convenient part of the car.

In Figure 4, the control valve or tap, which is shown connected by pipe connection 32 to the fourth part 16 of the device or apparatus first described, is provided with a pipe for connection with the induction pipe. The valve or tap consists, as shown in Figures to 8, of a cylindrical body 34 with a flanged head 35 thereto marked Off, Vap, Air, said member 34 being longitudinally and centrally bored to receive a plug 36 fitted with operating knob 37 with pointer thereon, said plug towards its lower end being provided with a horizontal bore 38 extending therethrough and a horizontal bore 39 extending from said bore 38 to the peripheral wall of the plug 36, which plug at its upper end is provided with a recess 40 for the engagement therein of a spring-pressed ball 41 to hol-d said plug 36 in its midway position, indicated by Vap on the head 35, .and in this position the bore 33 of the plug 36 aligns with the ports 42 and 43 in the body of the valve or tap 34, said ports 42 and 43 communicating respectively with pipe connection 32 to the moistener or mixer, and by pipe connection with induction pipe of engine so that there is free passage for the admission of water vapour (water and air mixture) to get outJ of induction. But on turning operating knob 37 to position Air on Figure 5, bore 39 and bore 38 register with ports 43 and 44 in the body of the valve or tap 34, allowing of the admission of extra air to induction pipe to act asa brake means and also as a cooling means on turning plug to position Off, then ports 42 and 44 are in communication, but nothing takes place as there is no suction on the lnoistener or mixer'.

It will thus be seen that one of the main objects of the invention is to provide apparatus or` devices as above set forth which are fool-proof and cannot get out of adjustment; are automatic in action and supply just the required amount of atomized water at all or any engine speed; ensuring complete combustion and the absence of any residue which in the ordinary way produces carbon deposits, pitted valves and other undesirable results.

A fuel moistening device for internal combustion -engines comprising a main body section providing a vaporizing chamber having an outlet passage, an air intake section fitted to the body section and including a cup-like member projecting into the said chamber, a water collecting chamber said air intake section also having a passage communicating with said water collecting chamber, through one wall thereof a section filtering means fitted into the air intake section and having a central bore and a recess and forming another' wall of said water collecting chamber, and a hollow valve having per forations therein and operating in said cuplike member, said valve also having a stem extending through the air passage of said intake section, and a spring for normally maintaining said valve away from the outlet passage of the main body section.

In testimony whereof I have affixed my signature hereto this 30th day of July 1925.
